Touch display panel

1. A touch display device comprising: a touch display module comprising: a TFT substrate; a color filtering substrate; and a liquid crystal layer between the TFT substrate and the color filtering substrate; wherein a first electrode layer is formed on a surface of the color filtering substrate facing the TFT substrate; a second electrode layer is formed on a surface of the TFT substrate facing the color filtering substrate; wherein the touch display device further comprises at least one supporting element elastically resisting against the touch display module from a side of the TFT substrate opposite to the color filtering substrate; the at least one supporting element is elastic; wherein: the first electrode layer comprises a plurality of conducting lines intersecting with each other to form a mesh; a plurality of through holes is defined in the first electrode layer; the first electrode layer comprises a plurality of nodes; and each of the plurality of nodes is formed where two conducting lines intersect with each other; wherein the second electrode layer comprises a plurality of touch sensing electrodes spaced apart from each other; the plurality of touch sensing electrodes forms a self capacitor structure configured for sensing touch position; wherein the second electrode layer further comprises a plurality of force sensing electrodes; some of the plurality of touch sensing electrodes each defines an opening; each of the plurality of force sensing electrodes is located in one opening, spaced apart from and surrounded by one of the plurality of touch sensing electrodes; wherein each of the plurality of force sensing electrodes overlaps with one of the plurality of nodes; the plurality of force sensing electrodes and the first electrode layer form a mutual capacitor structure configured for detecting a touch force applied on the touch display device.
